Cavity wall insulation helps improve the energy efficiency of buildings by reducing heat loss through external walls. Installed between the inner and outer wall layers, insulation boards help maintain comfortable indoor temperatures while lowering heating costs.

Our range includes PIR (polyisocyanurate) insulation boards and EPS cavity insulation suitable for both full-fill and partial-fill cavity wall systems. These high-performance insulation materials provide excellent thermal efficiency while remaining lightweight and easy to install.

Cavity wall insulation is commonly used in new builds, home extensions and energy-efficient construction projects. Properly installed insulation helps improve building performance while meeting modern building regulation standards.
